A
You can create an array using the array() constructor. When calling array(), you can also initialize the array with pairs of keys and values. Here is a PHP script on how to use array():
<?php
print("Empty array:\n");
$emptyArray = array();
print_r($emptyArray);
print("\n");
print("Array with default keys:\n");
$indexedArray = array("PHP", "Perl", "Java");
print_r($indexedArray);
print("\n");
print("Array with specified keys:\n");
$mappedArray = array("Zero"=>"PHP", "One"=>"Perl", "Two"=>"Java");
print_r($mappedArray);
print("\n");
?>
This script will print:
Empty array:
Array
(
)
Array with default keys:
Array
(
[0] => PHP
[1] => Perl
[2] => Java
)
Array with specified keys:
Array
(
[Zero] => PHP
[One] => Perl
[Two] => Java
)
